Military outside the US. Hobbyist with a death wish. I barely trust the average LEO with a gun let alone a good dog.
Two such dogs come to mind. The first was a mal I met at Donovan's place during a trial. The guy had just imported it from Israel and was looking for advice. He was wearing bite pants as he heeled the dog around because every time he gave it a collar correction it nailed him in the knee. I suggested he send the dog back.
The second was a KNPV mal that scared the shit out of me when I worked it. Big and punishing. A friend was caring for the dog before the owner could pick it up and he tried to feed it one day. The dog took three fingers off.
These dogs could be excellent in the right hands. (I'm sure the first guy is dead.)
